Tracking bug for JXcore leveldown issue

[yaronyg]

David owes a clean repro to Oguz et al.

There is a leveldown module that comes bundled with pouchdb - it appears we are using a duplicate in node_modules

[deadlyfingers]

@yaronyg - leveldown module duplicated in:
www/jxcore/node_modules/leveldown and
www/jxcore/node_modules/pouchdb/node_modules/leveldown

We need to delete the duplicate -
Reference to solution: jxcore/jxcore#597

Also for testing in desktop do I strictly need to use jx app.js or is it okay to use npm app.js in this localhost dev case?

https://github.com/thaliproject/postcardapp/blob/master/www/jxcore/package.json directly specifies leveldown 1.3.0 but it also specifies pouchdb 3.6.0. Now pouchDB 3.6.0 specifies leveldown as a dependency (see https://github.com/pouchdb/pouchdb/blob/849fd7ae440824c46d3219c90dea4e49caf08693/package.json) but it uses version 0.10.2.

That is why you end up with two different versions of leveldown.

But the real question is - why does this matter? Do we know that the two versions are conflicting?

If so there are several options:

Option 1 - Change postcard's package.json to use leveldown version 0.10.2
Option 2 - Change postcard's package.json to use leveldown version 1.4.1 and then change the pouchDB version to 5.0.0 which uses leveldown version 1.4.1.

I'd prefer option 2 but that is just me.

I got it working in localhost by deleting both 'leveldown' locations.
Then doing npm install leveldown in www/jxcore dir.

Or if I change the npm start command to use jx instead of nodemon in package.json

"start": "NODE_ENV=development jx ./app.js"

Then doing jx npm install leveldown in www/jxcore dir works in localhost.

@yaronyg option 2 (fixing leveldown versions) works in desktop - but need to copy in the right 'mockmobile.js' into thali module
